Synthetic-aperture radar (SAR) is normally used in an active mode for airborne ground surveillance. Passive SAR has also been demonstrated using DVB-T signals from digital TV broadcasting masts acting as illuminators of opportunity. However, simultaneous active and passive SAR has not yet been possible. In this paper, we compare active and passive SAR and describe a system which can perform acquisition of both active and passive UHF-band SAR data in an airborne platform.
